Hyperjaxb3：是否可以避免在PO样本上创建Items表/类？

Question

I'm trying to avoid join classes creation. I tested some binding configuration but can't seem to get it done.

In PO Sample from git sources on tag 0.6.0 ejb/tests/po-customized, I tried some configuration.

First, I added join-column as one-to-many mapping in bindings

bindings.xjb

...
        <hj:persistence>
            <hj:default-one-to-many>
                <orm:join-column />
                <!-- <orm:join-table /> -->
            </hj:default-one-to-many>
        </hj:persistence>
...

This only change the annotation in getItem, from JoinTable to JoinColumn.

Also, I tried to override xsd mapping by telling it to add a list directly. the following code doesn't work, but it's the general idea of what I've been trying... (never get something like it to work)

bindings.xjb

...
        <jaxb:bindings node="xs:complexType[@name='PurchaseOrderType']">
            <hj:entity>
                <orm:table name="po" />
            </hj:entity>
            <jaxb:bindings node=".//xs:element[@name='items']">
                <hj:one-to-many>
                    <orm:join-column name="PO_ID" />
                </hj:one-to-many>
            </jaxb:bindings>
        </jaxb:bindings>
...

Is it possible to generate PurchaseOrderType with this definition? (some xml annotations omitted)

...
public class PurchaseOrderType ... {

    protected USAddress shipTo;
    protected USAddress billTo;

    @XmlElementWrapper(name="items")
    @XmlElement(name="item")
    protected List<Item> items;

    protected XMLGregorianCalendar orderDate;
    protected Long hjid;

...
    @OneToMany(targetEntity = Item.class, cascade = {
        CascadeType.ALL
    })
    public List<Item> getItems() {
...

Note in this code, I'm pointing directly to generated Item, and not Items.Item.

Thanks a lot!

This worked in HJ2 but was is not implemented in HJ3 yet. Here's an issue for this.

In principle, the XmlElementWrapper plugin you mention is a way to go. I've just never tested it with HJ3.

If you want this feature, please file an issue here , I'll see what I can do.
